Improve performance of as_compressed_state (#141800)

Browse Source 
We have to build all of these at startup.

Its a lot faster to compare floats instead
of datetime objects. Since we already have to
fetch last_changed_timestamp, use it to compare
with last_updated_timestamp since we already know
we will have last_updated_timestamp
